Cubic Spinel XIn2S4 (X = Fe, Co, Mn): A New Type of Anode Material for Superfast and Ultrastable Na-Ion Storage

Constructing hierarchical structures with heterointerfaces is an effective approach for developing high‐efficiency energy‐storage anodes for sodium‐ion batteries. In this study, MoS2@ZnIn2S4 nanorods are designed and fabricated for structural improvement. Theoretical calculations reveal that there are two different MoS2‐ZnIn2S4 heterointerfaces formed by MoS2 with the Zn and In facets of ZnIn2S4, which generate directional built‐in electric fields that provide additional driving forces for facilitating electron transfer. These two heterojunction interfaces, especially the MoS2‐In facet, exhibit enhanced Na+ adsorption energies and reduce Na+ diffusion energy barriers. The multistep reactions of MoS2 and ZnIn2S4 reveal a synergistic effect that promotes the entire electrochemical process. Furthermore, the synthesized hierarchical nanorods composed of nanosheets offer abundant Na+‐storage sites and multidirectional migration pathways and, importantly, accommodate the excessive volume change. Benefiting from the heterointerfaces and hierarchical structure, the composite electrode exhibits excellent electrochemical performance, with high reaction activity and rapid electron/ion diffusion kinetics.

Photocatalysis has shown tremendous potential to solve world problems with environmental pollution and energy scarcity. In this list, ternary metal chalcogenides ZnIn2S4 (ZIS) has garnered attention over others due to its superior visible light capability, low-cost, excellent chemical stability, and substantial interdisciplinary interest. Recent investigations have shown the development of a wide range of ZIS nanocomposite structures. Several modulated strategies are involved in enhancing the activity of ZIS-based nanocomposites. In this review, various synthesis strategies of ZIS are added. Furthermore, we observed the advantage of the ZIS electronic structure for water splitting along with pollutants removal, organic synthesis, sensing, nitrogen fixation, and many more. Modification leads to enhanced material effectiveness for hydrogen production. This review hopes to inspire further research into this promising material for application in efficient energy and environment by showcasing the state-of-the-art of ZIS photocatalysts. In this context, we discussed the mechanism behind hydrogen production.
